The Conservative was found to have explicit videos of children “clearly under 12” – but he escaped without any action being taken, it is claimed

Last night the Director of Public Prosecutions was urged to investigate allegations that the politician was stopped by customs while driving back to the UK via Dover.

The videos and paperwork that were taken during the 1980s incident have subsequently gone missing.

“It’s yet another example of intelligence going missing”

Tom Watson, Labour MP

The Customs officer has spoken to detectives on Operation Fernbridge, an inquiry into allegations of sexual abuse by people including high-profile figures at the Elm Guest House in Barnes, south-west London.

The Labour MP Tom Watson, who has led calls for a comprehensive probe into historic child abuse, said he was writing to Alison Saunders, head of the DPP, to ask her to examine evidence.He said: “It’s a remarkable revelation. If true, it shows a crime was not investigated but also it is shocking because it’s yet another example of intelligence going missing.”

The senior Tory’s name is said to have been included in a dossier alleging paedophile activity in Westminster, which the Government admits has probably been destroyed.
